This is from Instapundit from which I have taken up one of the comments.
THE INTENSITY OF THE IMMIGRATION DEBATE, EXPLAINED:
Across the West, existing voters won’t give the left the power it wants, so they’re importing new ones.
And this is the comment that puts its finger right on the issue:

They hate themselves and they hate you as well, whatever else they may say.
